VQ35HR Engine/VQ25HR Engine

The VQ35HR and VQ25HR are the two newest engines in the VQ series, developed as part of Nissan's ongoing pursuit of the ultimate in responsive, smooth-revving powerplants. From the time the series debuted in 1994, the VQ has been highly acclaimed* for its powerful evolution in line with the concepts of simplicity, compactness, low friction and responsiveness. Both of these V-6 engines have inherited the core elements of earlier VQ generations, with further enhancements to boost their capability to rev to high speeds and improve their smooth operation. They have evolved into next-generation FR V-type engines that offer a smooth and comfortable driving experience.

*The VQ is the only engine in the world to win a spot on Ward's &quot;10 Best Engines&quot; list for 14 years running, starting from the inception of the list in 1995 through 2008.

New VQ35HR engine

Features

Revs up smoothly to high speeds Better fuel efficiency and lower exhaust emissions

Adding a ladder frame to support the crank strengthens rigidity, which dampens vibrations and greatly reduces friction at high speeds.

Isometric exhaust manifold Making the left and right exhaust manifolds of equal length produces a clearer and more dynamic exhaust note. This isometric design prevents unwanted interference between the exhaust pulsations each cylinder produces following combustion, minimizing undesirable sound components. Exhaust efficiency is also improved, producing extra torque at low to mid speeds.

Ladder frame

CVTC installed on both the intake and exhaust

The CVTC (continuously variable valve timing control) system sets the optimal opening and closing of the intake and exhaust valves according to the engine's speed. The hydraulic CVTC expands the valve angle on the hydraulic Hydraulic CVTC Electromagnetic CVTC (e-VTC) intake cam side, while an e-CVTC (electromagnetic CVTC) system is used on the exhaust side.
